Abstract
The utility model discloses an irregular double metal finned pipe, composed of a basic pipe and fins which are uniformly arranged on the outer wall of the basic pipe. The utility model is characterized in that the inner wall of the basic pipe is uniformly provided with continuous or intermittent spiral grooves. The utility model has the advantages of simple structure and good heat exchange effect, and is particularly suitable for fluid having high viscosity and low flow speed.
Description
The utility model relates to a kind of bimetallic fin heat exchange pipe that heat exchanger is used that is used for, and relates in particular to a kind of special-shaped bimetallic finned tube with interior reinforced structure.
The bimetallic fin heat exchange pipe that generally uses is made up of the aluminous fin of metal parent tube and parent tube sheet wall at present, parent tube inner wall smooth or set up directly helps to improve the heat exchange effect, medium is that high-viscosity fluid and flow velocity are when slow in pipe, usually increase insert in the parent tube, to destroy flow boundary layer in the pipe, improve the coefficient of heat transfer, but increase insert and do not increase the intraductal heat exchange area, and insert must be fixed, special when pipe fitting is longer insert, the die heat exchange effect of above-mentioned prior art of fixing difficulty especially is difficult to further raising.
The purpose of this utility model provides a kind of simple in structure, and the heat exchange effect is sent out, and has both increased the intraductal heat exchange area, does not increase caliber again, is specially adapted to the bimetallic finned tube of the low flow velocity of higher tack medium.
The utility model is made up of at the aluminous fin 2 of parent tube 1 outer wall parent tube 1 and cladding, and its principal character is that parent tube 1 inwall is provided with spiral channel 3.Spiral channel 3 can be continuous, also can be interrupted.
Because parent tube inwall of the present utility model is provided with spiral channel, has not only increased the parent tube heat exchange area, and can effectively increase the turbulence level in tube fluid boundary layer when high-viscosity fluid low speed flows, thereby the utility model is simple in structure, the heat exchange efficiency height.
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is that the A of Fig. 1 is to view.
Referring to accompanying drawing: parent tube 1 is a steel tube, behind the outer suit heavy wall aluminum pipe of tube wall, and rolled fin 2, parent tube 1 inwall is offered helicla flute 3.The groove depth of helicla flute 3 is 0.5-3mm, and spiral head number is 5-70.Whether helicla flute 3 can be determined according to the heat exchange needs continuously.
Claims (2)
1, a kind of special-shaped bimetallic finned tube of being made up of parent tube 1 and fin 2 is characterized by parent tube 1 inwall and is provided with spiral channel 3.
2, by the described a kind of special-shaped bimetallic finned tube of claim 1, it can be continuous it is characterized by said helicla flute 3, also can be interrupted.
